    • Far-infrared optical transmission through asymmetrical ferroelectric films 

      Mohamad Nazri, Abdul Halif (Research India Publications, 2005)
      Investigation of far-infrared (FIR) spectroscopy for symmetrical ferroelectric (FE) films are discussed theoretically based on the basis of the Tilley-Zeks (TZ) model using Landau free energy expansion, Landau- Khalatnikov ...
    • Journal Impact Factor 

      Mohamad Nazri, Abdul Halif (Universiti Malaysia Perlis (UniMAP)Pejabat Timbalan Naib Canselor (Penyelidikan dan Inovasi), 2007-01)
    • A numerical approach of Polarization profile for First-Order Ferroelectric film system using Finite-Difference method 

      Mohamad Nazri, Abdul Halif; Junaidah, Osman (Kolej Universiti Kejuruteraan Utara Malaysia, 2005-05-18)
      A detail account of numerical calculations using Finite-Difference Method (FDM) to calculate the polarization profile in first-order ferroelectric (FE) film system is given. For film, both symmetric and asymmetric cases ...
    • Oscillatory dynamical switching system of bulk ferroelectrics 

      Mohamad Nazri, Abdul Halif; S. Daud; Junaidah Osman (Science Publications, 2005)
      This study gives a detailed account of calculation of the bulk ferroelectric (FE) oscillatory dynamical system switching for first and second-order phase transition, respectively. All the formalism is delineated in the ...
    • The phenomenological theory of Far-Infrared spectroscopy for a ferroelectric fim system 

      Mohamad Nazri, Abdul Halif; K.H. Chew; Tilley, David R.; Junaidah, Osman (Malaysian Institute of Physics & National University of Malaysia, 2004-10-05)
      We describe a detailed phenomenological theory of far-infrared (FIR) spectroscopy in symmetric and asymmetric ferroelectric (FE) film for the second and first-order phase transition. For the asymmetric FE film, a silicon ...
    • The physics of Tsunami: basic understanding of the Indian Ocean disaster 

      Mohamad Nazri, Abdul Halif; Sharifah Norfaezah, Sabki (Science Publications, 2005)
      This study gives a simple physics explanation behind the Indian Ocean earthquake, called December 26th‘s Tsunami. The explanation based on physics energy conservation and wave properties have been used to understand this ...
    • Surface state on first-order ferroelectrics 

      Junaidah, Osman; Tilley, David Reginald; Rosy, Teh; Ishibashi, Y.; Mohamad Nazri, Abdul Halif; Khian, Hooi Chew (Springer Berlin / Heidelberg, 2006)
      In the presence of a surface the Landau-Devonshire equations of ferroelectricity must be extended to include a boundary condition. For a ferroelectric with a second-order transition in the case when the polarization p(z) ...
    • Theoretical investigation of far-infrared optical behaviors in asymmentrical first-order ferroelectrtric thick film 

      Mohamad Nazri, Abdul Halif; Khian Hooi, Chew; David R., Tilley; Junaidah, Osman (Universiti Putra Malaysia (UPM), 2005-12-06)
      This paper gives a detailed, fully numerical approach to investigate the behavior of far-infrared (FIR) waves in the first-order of asymmetrical thick film ferroelectrics on semiconductor substrate. The theoretical calculation ...
